The two obsidian sources from the island of Melos (Greece), Agia Nychia and Demenegakion, are chemically characterized by three complementary analytical techniques. Ion beam analysis (IBA) comprising particle induced X-ray emission and particle induced gamma-ray emission, neutron activation analysis (NAA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is applied to ...

Sugarcane problems in germination will effect on growth and the yield that is not optimal. The solution obtained from these plant regulators soaking storage time bud sett seedling before planting. This study used a factorial experimental method with first factor being consisting of 3 levels, namely 0 days (control), 1 day, 2 days. second was PGR which consisted control (without soaking), NAA + ...

In the present study, an attempt was made to induce rooting from single-node cuttings of hybrid aspen (Populus tremula L. × P. tremuloides Michx.) with different concentrations of Indole-3-acetic acid (IAA), Indole-3-Butytric acid (IBA) and 1-Naphthylacetic acid (NAA). Among the three auxins used, 0.54 mM NAA showed more effective induction on rooting as compared to IAA and IBA at the whole lev...

studies have shown that rooting substrate is one of the effective factors at rooting of hard rhizogenetic plant such as henna. the purpose of this study is to determine an appropriate concentration of naphthalene acetic acid (naa), indole butyric acid (iba) and salicylic acid (sa) on rooting of henna. present study showed that there was a great variation in most of the measured characters at p<...

In this research, a factorial 4×3×4 with 4 replications in Completely Randomized design was used to study the effects of different auxin treatments (4 levels), pH(2 levels) and cultivars (3 levels) on regeneration and rooting of in vitro shoot tips excised from shoots cultured on media supplemented with 1.5-2 mg/l BA. The results showed both auxins (NAA and IBA) produced callus in the bases of ...
